All these studies that show that men are naturally more intelligent because their brains are larger amount to the same thing, but racism is out of vogue, so let's use it to justify pre-existing sexism this time.
If 3 women published a scientific paper with the conclusion, "girls rule, boys drool," you wouldn't feel at least a little suspicious of the authors' intentions?
and also the idea is not to justify sexism, but to provide another possible reason for why a trend seems to perssist after apparent bias is eliminated. This is in response to the idea that oppression is somehow responsible for 100% of the gender-ratio gap.
I don't claim that biological reasons are the only reasons but I stress that they do in fact exist and that a violent response to suggesting that they might exist is not normal.
To use this studies to be sexist, is the wrong idea ,as the memo's author explained, because there is overlap between the populations and while on average one is better (in that respective function) then the other, that does not preclude that someone from the second group is better then someone one the first.
In other words, the result on hiring based on merit alone is better then both: - hiring only males - hiring based on prescribed gender quotas.
and by the way, there is studies that indicate that woman are better at empathy ( a sign of emotional intelligence): https://www.ncbi.nlm.nih.gov/pubmed/19476221
